How to Take a Blood Pressure Manually

How to Take a Blood Pressure Manually

– In this video I’m gonna break down and go through with you how to take a manual blood pressure. (calming music) Shout-out to PinkCubs1 who commented on my YouTube video suggesting that I make a video on how to take a manual blood pressure. This one is for you. Guys if you are, like me, a nurse or just into all things nursing, consider subscribing to my channel ’cause I have a lot of
nursing stuff coming your way. And if this video is helpful to you or you like it or whatever,
please give it a thumbs up. Now let’s get into the video. Okay, so what you’re gonna need now in making a manual blood pressure is of course a stethoscope and
a manual blood pressure cuff with a sphygmomanometer on it. Very hard work to say, that. So here we go. One of those. So the first thing you’re
going to want to do is find the brachial artery. And finding that is, on your elbow or your antecubital fossa,
and go in the middle. and midline. Right there I can feel it straight away. I can feel my fingers, I
can see my fingers pounding and I can feel it pounding. Okay, right arm, midline,
middle of your elbow and go in. There it is. Easier to find in healthy people, but in overweight people, elderly people it’s harder to find, and
what I normally do is I take my stethoscope,
put it in the middle, move it to the side a little bit. So this right here is
the sphygmomanometer. Now I’m only gonna say
that once this video ’cause it’s a really hard word to say. And I’m just going to call
this the dial from now on. And it goes from 20 to 300. Now the textbook would tell you to dial, to pump the bulb up to about
10 to 20 millimeters of mercury above the expected systolic. Now we’re not psychic so
we can’t just say, yeah your blood pressure’s gonna be 120, so there’s a way that you
can expect the systolic, and the way that we do that
is to find the radial pulse, which is right here. There it is. And have a straight arm. There it is. And you would pump the bulb up and when you don’t feel the pulse anymore that is the estimated systolic value. And then when you release it, when you feel the pulse again, that’ll be the expected again. So you can do it both ways. All right, so that’s how you would do it. And then you would go
ten to twenty above that, so if my blood press- if I had my brachial pulse here and I was pumping it, pumping the bulb and at 1:30 I couldn’t
feel it anymore here, that’s my expected systolic, okay. And then if again if I release the bulb and I started feeling the
pulse here again at 1:30, again that is the expected systolic. All right, so this is the bulb, this is the pressure valve control and you’d hold it in your right hand if you’re right-handed,
left if you’re left-handed and it opens and closes. Now it is closed towards you. This was hard for me to understand when I started doing blood pressures. I had it open, kept
pumping, and I was like Ooh, nothing’s happening,
nothing’s happening! Oh, well, nine times
out of 10 I had it open. So it takes a while but now
I always have it closed, and I remember this by
closed towards me, open away. Okay? So now it’s closed towards me. And that’s all the parts
of the blood pressure cuff. Obviously you have the actual
blood pressure cuff here. My blood pressure cuff
has got a little indicator for the artery, and for the
left arm and the right arm. And you would line it up
with the brachial artery, so I’ve got it on my left
arm and here it says left arm and I’ve got it lined up
here with my brachial artery. And you go about two fingers
above the crease of your elbow. And that’s how you know
you’ve got the cuff in the right spot. So taking your blood pressure is a visual and audio assessment, so you’ll
need both your stethoscope and your eyes to have a look at the dial. Okay, so what you would do,
put your stethoscope on, put it here on the brachial
’cause you found it before. Now I don’t have enough arm
so I’m just going to see if that stays just about there. And then the pressure
valve, push it towards you to have it closed. And then let’s say my
expected systolic is 120. So I’m going to pump it up to 140 and then I’m going to
release it very slowly. And then the first boosh
that I see and hear is my systolic. And the last boosh that I see
and hear is the diastolic. Now remember, you can
sometimes see the little tick go like that, but you’re
not actually hearing it. That’s not your systolic. It’s when you hear it
and see it, all right? So close that, I’ll pump it up to 140, release it slowly, okay. I can see the dial go like this and obviously I can’t tell
what my blood pressure is cause I’m not actually listening to it, but those are the steps
you would go through. Okay, so now that we know how we’re gonna do the blood pressure,
what to listen out for, I’m going to show you how
to do it on a patient. Okay, so now we’re going
to take a blood pressure on my patient, who today
looks a lot like my husband. – Hey you guys. – Nice enough to volunteer today. Okay, so first off we need to estimate his systolic blood
pressure, and by doing that we need to feel for his
radial artery, radial pulse which is just down there, there it is. Nice and strong. And what you do is close
your valve, pressure valve towards you, close the valve, feel for the radial pulse here. So pump it up, look at this dial. When you can’t feel the
radial pulse any more is the expected, so that’s about 105, I can’t feel the pulse anymore. Pump up a little bit more, release when you feel the radial pulse again is his also expected systolic. That came up a little
bit lower, at about 90 so I can sort of
guesstimate it’s going to be between 90 and 110. So I’m gonna pump it
up 10 to 20 millimeters of mercury above my expected systolic. So I’m gonna pump it
up to about 130, okay? So I’ll close the valve
towards me, closed. Find the brachial pulse right there, put your stethoscope there, right there and then you pump it up. We’re going to pump it up to about 130 and then we’re going to
release that pressure valve very slowly, and we’re
going to look at the dial and the little tick, and it’s
gonna go boof, boof, boof. The first boof that you
hear is your systolic, the last boof that you
hear is your diastolic. Okay, so you gotta look and listen. All right, here we go, up
to 130, release slowly. Boof, boof, boof. Okay, so I heard the
first boof at a hundred and the last boof I
could hear was about 62. so my patient’s blood
pressure is 100 over 62. I hope this video has given you
a little bit more confidence and understanding in the
manual blood pressure. It’s not an easy thing,
but once you get it it’s gonna get much easier from here. Now if you have any questions, pop them in the comments
below, or even better if you have any video suggestions that you would like me to do, pop them in the comments below as well and I will make sure to
get back to all of you. And guys, remember as always,
listen with your heart. But my husband, who is
a non-medical person, is now gonna try and
take my blood pressure. He’s a little bit nervous. – (laughs) I hadn’t
thought what I was doing. (upbeat music)

    This video is so informative. Thank you so much Nurse Jenny!

  • Dharrel Kabiling

    Great video Nurse Jenny i take metropolol 2 times a day when should i take my bp am or pm and how many times do i have to take my bp i have mvp sinus arrythmia and palpitations i aldo have a sphygmomanometer

  • blank blank

    Can you make a video specifically on how to turn the knob? I need little memory tricks. Such as closed towards me, open/ towards patient. But more detailed instructions on how to hold it and what not bc I am still so awkward with it. THANK YOU! This will help me get through nursing school!

  • Michele Macanoni

    Very nice video! It helped me a lot. Thank you (:

  • Roger J. Fontana

    Oh wow. You two are so cute. Your husband is handsome. He’s a great patient.
    I know, that it’s very hard to teach and explain it! Once one of my students said, he couldn’t hear anything. I borrowed my expensive stethoscope to the student. And – he still couldn’t hear anything.
    So. We listened together. He with my expensive stethoscope and I with his cheaper one. And I could hear it properly. And – he couldn’t still hear anything.
    I checked his stethoscope and it was alright.
    I asked him “tell me. you don’t hear anything. WHAT do you hear then?!” He said “I can only here something like a whoosh, that comes and goes. But there’s no beep sound at all!”

    Sometimes, your students watch too much tv.
    And sometimes, you need to be much better in explaining, WHAT to EXPECT, noise wise.
    It was a funny situation.

    Can you estimate the diastolic bp

  • Pranav Deo

    Thank you so much , i am a teen and this video has been beneficial for measurement of my dad's blood pressure , also checked mine came out to 106/70 .
